This invention has relation to tiles for the construction of sewer pipes and other conduits of large size and has for its object the provision of a tile of sector formation, hav- 5 ing improved means for the solid and substantial connection in series to form a cylindrical tubular structure, which may be built up and completed in cylindrical sections before being laid in place. I

The invention consists in the novel construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, illustrating a preferred embodiment of my invention. Figure l is an end view of ya tube or conduit buil-t up of the tiles constituting my invention; A

Figure 2 is an enlarged view of a portion of the conduit showing the construction and mode of fitting lengths in the tile sectors;

Figure 3 is a fragmentary sectional view showing the right hand end portion of sector l;

Figure 4 is a sectional view on line 4-4 of Figure 2.

The tile is of the general form of the sector of a circle and is composed o f burnt clay of the usual character. The several connected sectors forming the circle or pipe are generally designated by the reference character A., and for purpose of detailed description wlth more speciiic reference to Figure 2, ad jacent tile sectors are designated by the ref erence numerals 1 and 2. Each sector for the purposes of the invention is of hollow construction with longitudinal channels 3 crossed diagonally bywebs 3a which impart the requisite strength and stability to the structure. The dimensions of the tile will vary according to the special uses made of it and the required dimensions of the sewer or conduit. Generally, such tile will be three to four feet in length, seven inches in thickness and of a diameter of six-ty inches, outside measurement. The conduit may comprise any desired number of sectors which will be controlled by the diameter of the sector and the diameter of the completed pipe or conduit. The construction features constituting the invention reside in the formafon 'of the "jointed adjacent 'sides of the sectors.- Y Y c .l

l The side edges of the tile sectors are formed withjinterlocking tongues"l and grooves,` and asI shown inldetail in Figure 2, the sector l is `formed'wat its outer side yedge with a semidove tailed tongue l4 having its outer surfacejcoincidentjwith' vthe, periphery 4of the sector whilea dove-tailed tongue 5 is carried by theisider edge of the sector l spacedfrom the` senii-dovetailed tongue 4,'between the innerfand outer edges of thesector. The ad'- jacent inclined faces of the tongues 4 and 5 define a dove-tail groove 4a in the edgewall ofthe sector. l, while a semi-dove tailed groove 'alis formedfatthe inner side edge of vfthe l sector l adjacent the dove-tailed t'ongue5`.f` l c r'lhe n eeting side edge of the adjacent tile sector 2 is fashioned with tongue and groove for interlocking Aassociation with the ade i jacent edge ofthe tile'sector l and has at its inner side edge a semi-dove tailed tonguel 9 received inthe semi-dove tail groove 5a and a dove-tailed tongue 8` spaced from the tonguef9 and the outer side edge'ofthe'tle" sector `2 received in the dove-tailed groove 4a."V Thev adjacent inclined faces of thel tongues 8 andv 9` form agdove-tailed groove' 9to"receive"the dove tailed tongue 5, while the 1 semi-.fdove-tailed groove V8a atrthe'outer' sideedge? of .the tile sector 2 receives the semidove'tailed tongue' 4, the interlocking engagement between the side edges of the tile sectors l and 2 being clearly illustrated in Figure 2. The relative dimensions of the tongue and groove connections are such that when the tile sectors l and 2 are assembled, the outer edge of the tongue 4 abuts the groove 8a, while the outer edge of the tongue 9 abuts the groove wall 5a. The adjacent side and end walls of the tongues 5 and 8 being spaced from the walls of the associated grooves 4a and 9a. The intervening spaces are filled with a binder, such as cement or concrete for the permanent ,connection of the tile sectors, the binder preventing relative movements in any direc-tion of the associated sectors.

In assembling the sectors to form a tube' or conduit, they are moved into position lengthwise of the sectors, the tongues sliding into their respective grooves. The binder of cement or concrete may be introduced into the intervening spaces between the tongues and grooves by the action of compressed air or the like, and moved lengthwise of said spaces to completely fill them while the; sec.- tors are being assembled. An additional cement or concrete binder is provided for the joints between the sectorsV for the pxzevisiplx,

of relatively deep pockets 6 extending 1n- Wardly from the outer ends of the dove-tailed tongues 5 and 8 that register with relatively shallow pockets 7 in thebottem walls ofthe recesses 4a and 9a. The cement or concrete. binder completely filling the ockets as shown in Figure 2, for amore e 'ective seal' for the tile sectors. The cement or concrete binder is designated by the reference numeral l0 and completely iills they intervening spaces and pockets present in the joints between the assembled tile sectors,

While there is herein shown and described .y the preferred embodiment of the present invention?, it is nevertheless to be understood that minor changes may be made therein.

without departing from the spirit and scope Of the invention as claimed.

I claimzy A tile for the constructionof tubesor conduits for sewersY and the like, consistingjof al sector of' burnt clay formed at the sides with dove-tailed tongues andgroovesy the inter- L mediate tongues at one side being in staggered relation to the tongues. at the other side, and of'greater length and width thanv the grooves,V whereby, interiitting tongues and' grooves are. spactnil apart on: all., sideS.,;

for the reception ofeement lli'n sthe outermost tongue being formed an adapted t0nx abut against? thefbottom` off the coinciding groove5 the inter-mediate interttinggrooves and tongues being recessedat opposite points to ferm channels fon the reception ofrcement filling.

In testimony whereof Iaix myk si,`g;n:1ture.
